Be it known that l, Ger Lann, a citizen oll the United States.y residing at Philadelphia. in the county etv Philadelphia and Stat-e et Pennsylvania, have invented certain 5)ew and useful Improvements in Automatic ilers. i

VThis invention relates te automatic oilers,V and for one o-its primary objects the previsien os'f an improved controlled feed jriler ior Ause on i antornobiles,V Vpneumatic spring'or vcushien,devicesgsnch 'tor example as the eswng-honse air spring` andthe Another Vabject olii' my invention Aresides in the provision oan improved automatic oiler so constructed Athat the .parts may be readily adjusted withouttaking the device am. v

lnetherobject of my .invention resides in the Aprovision"of an improved form of feed control mechanism n tation to st ldard'forms ot'oil cupsgfwithout necessitating alterations thereof.

' Referring now tothe drawingthe oil cup iS. designated by the refcce munter 7, the

grraten" the sfeer ie- ?e a elan View cup heingvprovided a neck ,8 'reduced its lower end and externally threaded as p Jfeed cliennel iiimtheneclr which comnninucfates ythe interiorlot the upj' reduced' in diameter a short'dis'tancetron the jtopof theneck leaving an annular. shoulder'9 adaptedito formV a seatfoifthe sprinfr 10,Kthe i'nnction of which will hereinafter rbe set -forth. @lt the ybottom the neck .is constructed to provide a valve seat 11. The cup is provided with any suitable form of cover, such for example as the'bayonet joint lid 12.

The flowV from the cnp is controlled by means ofthe valve 13i such valve being preferably conical in shape and being provided with a long .stem 1LL which has a diameter considerably less than the internal diameter Specicatien of Letters Patent.V

of thel neck 8, particularly with respect to those portions above the valve seat. The valve stem projects well within the cup andit is externally threaded at its upper end,

such end being slotted as at 14 and sprung outwardly. i A; weight '15 is threaded on the upper end of the stem and is held in any ldesired position of adjustment by the spring action oi the slotted portion of the stem. Any suitable member may be used for such weight. The spring 10 is interposedV between the lshoulder 9 andthe weight'l and serves .to hold the valve 13 in closed position.v The seat 11 is relatively shallow, that is to say the portions with which the valve 13 comes in contact are relatively very short in depth. the purpose of which will appear.

The operation of the oiler is as follows. assuming that the oiler is used on an airspring of an automobile, for example, there is ordinarily no vertical jolting of sulicient sharpness to cause the weight 15 to unseat the valve 13 against the vpressure of the spring 10. However'7 with the car` in motion there Ais snfiicient lateral motion or vibration to cause the valve stem 14 and weight 15 to swing somewhat like an inverted pendulum, causing the'valve 13 to rock on its seatV in 4the manner illustrated in Fig. 2. This partial unseating of the valve permits oil to tl'ow in suflicient' quantities to liibricate the air spring. Thep'eciiliar operationfof lthe valve just described is br'onght about because the valve 4is made top heavy by virtue of the Yp1'. ovis'ion the Vweight 15' atthe'top of the valve' stern, andV because sutticient space is provided theneclrty to permit the valve stem to sway and because the valve seat is relatively shallow. rThedegree of opening and therefore the rate of oil feed maybe ad jnsted by means of the weight 15 which when shifted n'otwonly alters'the compression'of meewegen natre basate 'of the any@ the emi@ www 'whicheees if ess'ble. 'adjust they` teiof' eed very clsely to thea'inonnt des ed.V It will be a ma' when the' that@ .eases a@ valve will beimmediately returned to 'its seat by the action of the spring, thus cutting olf the flow of oil and eliminating wastage.

If the oiler be placed on the car at points where there is jolting in a vertical direction, as for instance on the axles, in addition to the unseating of the valve resulting from the swaying et the valve stem, before described,

'hand or, with a tool and turningh by vinserting a screw` driver, or t the slot 14. Itis thus not necessary to rethe'valve 'may be opened by reason of `the i fact that the inertia ofthe valve, valve stem and weight, when in motion may be` su'liicient to overcome the pressure or" the spring 10.

In assembling the device the stem 14 Ais passed through the neck, the .springV Y1() move the cup for purposes of adjustment.

Y It will bejseen from the. foregoing that oil cups of standard design may be readily equipped with Vthe automatic control valve mechanism, in Awhich connection it is to be slashed.

observed that with thev possible exception or' the valve seat 11 the standard forms of oil Vcups respond ver'y closely to thejstructure shown and described. VIt desired a seat could be provided in ythe standard types by a suitable reaming tool. It will be apparent that the cup may be used 'on any apparatus subject to suliicient vibration to unseat or partially unseat the valve.

',Another advantage incident to 4the; ar-' rangement is that the cup maybe readily "In Fig. '3, instead orvffslotting the valve stem, I riait the upper endon both sides,a's'V 1 through into. the cup, a shoulder'V in said vrat 15, and provide the weightl with van annular lip 1G which is slotted to receive the wire 17 adapted toV yieldingly bear n against the flattedvportions of the stem and thus releasably hold the weight in positions of. adjustment. In order to'reta'in the wire,

the .metal adjacent the slotsmay Vloe peened with as'uitable tool.
